摘要:
A solar cell of the present invention includes a collecting electrode (7) extending in one direction on a first principal surface of a photoelectric conversion section (50). The collecting electrode (7) includes a first electroconductive layer (71) and a second electroconductive layer (72) in this order from the photoelectric conversion section (50) side, and further includes an insulating layer (9) provided with openings between the first electroconductive layer (71) and the second electroconductive layer (72). The first electroconductive layer (71) is covered with the insulating layer (9), and the second electroconductive layer (72) is partially in conduction with the first electroconductive layer (71) through the openings of the insulating layer (9). The first electroconductive layer (71) has non-central portions (Lo) within a range of d 2 - d I from both ends of the first electroconductive layer, respectively, and a central portion (Lc) between the two non-central portions, in a direction orthogonal to an extending direction of the first electroconductive layer (71). A density S C of openings of the insulating layer on the first electroconductive layer at the central portion (Lc) is higher than a density So of openings of the insulating layer on the first electroconductive layer at the non-central portion (Lo).

摘要:
This invention aims to reduce and preferably to cancel the carrier collection limit effect in order to considerably increase the conversion efficiency. This improvement is achieved by a suitable modification of the amorphized layer thickness or even by discontinuities separating amorphizing beams or amorphized nanopellets.
摘要:
There is provided a groove machining tool supported in a holder and caused to move together with the holder in relative fashion along a scheduled scribe line over an integrated thin-film solar cell substrate to form a groove. The groove machining tool includes a tool body supported in the holder, and a blade tip part formed in a distal part of the tool body. The blade tip part includes a blade extending along a direction intersecting a direction of movement of the tool, at a first end along the direction of movement of the tool. The blade is tilted backward from the direction of movement of the tool in relation to a direction orthogonal to the direction of movement of the groove tool, as viewed from a bottom face of the blade tip part.

摘要:
Bei der Herstellung von mit Fingerelektrodenstrukturen (7) versehenen Dünnschichtsolarzellen aus amorphem Silizium werden die durch Fehlstellen im amorphen Silizium (4) verursachten Kurzschlüsse zwischen Grund- und Deckelektroden dadurch vermieden, daß zwischen der Grundelektrodenschicht (2) und der Deckelektrodenschicht (6) zumindest im Bereich der Fingerelektrodenstruktur (7) vor oder nach der Herstellung der aktiven amorphen Siliziumschichten (4) eine Isolationszone (11) durch zusätzliches Erzeugen einer Oxidschicht oder durch Wegätzen der Grundelektrodenschicht (2) erzeugt wird. Das Verfahren wird verwendet bei der Herstellung von großflächigen Solarzellen aus amorphem Silizium.
